The 18QHTF21-45.056-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 45.056 MHz. It utilizes LVCMOS output logic and functions with a supply voltage of 1.8V. The device features an Enable/Disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes Enable/Disable pin for active power management
• Utilizes a leadless SMD package for surface mount assembly

Oscillators Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring 1.8V operation
• Embedded devices utilizing standard crystal oscillators

Oscillators Procurement Notes

Verify the specific suffix OE against official Mercury Electronics documentation to confirm the Enable/Disable functionality and electrical characteristics. Ensure the 1.8V supply voltage aligns with system requirements. Cross-reference the 45.056 MHz frequency tolerance and load capacitance specifications from the manufacturer datasheet before integration.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V LVCMOS oscillator is required with remote enable capabilities. The small 2.0x1.6mm footprint suits space-constrained designs. Confirm that the standard oscillator type meets the phase noise and stability needs of the target application compared to TCXO or VCXO alternatives.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of standard crystal oscillators. The series offers various frequencies and supply voltages, typically packaged in leadless SMD formats. The -OE suffix denotes specific control features within this product line, distinguishing it from variants with different power states or output types.

Oscillators Replacement Considerations

Direct substitutes must match the 45.056 MHz frequency, 1.8V supply, LVCMOS output, and Enable/Disable functionality. Verify pinout compatibility and thermal performance. Consult Mercury Electronics for cross-reference lists or equivalent parts with identical electrical parameters and package dimensions.
